What is Q235B steel?
Q235B steel plate, a quintessential example of low carbon steel, is defined by the prestigious national standard GB/T 700-2006 'Carbon Structural Steel.' As one of the most prevalent steel products in China, Q235B is recognized for its affordability and versatility, suitable for a myriad of applications that do not demand exceptional performance.
The difference between Q235A and Q235B.
The difference between Q235A and Q235B: Both are quintessential carbon steels. As per the national standard GB700-88, the primary differentiation lies in their carbon content. Q235A boasts a carbon content ranging from 0.14% to 0.22%, setting it apart from its counterpart.
Typically, steel mills meticulously mark finished profiles on identification plates prior to dispatch. This practice enables users to discern whether the material is Q235A, Q235B, or another variant. With a design pressure of P≤1.6MPa and operational temperature spanning from 0 to 350ºC, the steel plate is crafted with a thickness of no less than 20mm.
The Application of Q235B Steel
Q235B steel is a cornerstone in the realization of civil engineering marvels. It is the trusted material for crafting robust steel structures used in the construction of both industrial and residential edifices. Its versatility extends to forming parts of power transmission towers, components of machinery, offshore installations, oil and gas platforms, automobile bridges, and a myriad of other infrastructural projects.
